Failure of either unit may trigger internal fault codes and result in loss of driveability, stalling, or an inability to start the vehicle.<\/p>\n<\/section>\n<div class=\"quick-summary\">\n<h2>Quick Summary<\/h2>\n<ul>\n<li>ECM and PCM removal each require about 0.8\u202fhours of labor.<\/li>\n<li>Relearn procedures add roughly 0.5\u202fhours after each replacement.<\/li>\n<li>Factory programming demands special equipment and vehicle\u2011specific calibration.<\/li>\n<\/ul>\n<\/div>\n<div class=\"info-section\">\n<p>When a 2014 Chevrolet Spark begins to exhibit intermittent power loss, unexpected stalls, or transmission irregularities, the electronic control modules are often the culprits. This guide explains what the ECM and PCM do, where they live, how they are replaced, and what steps follow the install. By the end, you will understand the labor involved, the programming requirements, and how to recognize the most common symptoms.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2014 Chevrolet Spark<\/h2>\n<p>The ECM in a 2014 Chevrolet Spark interprets sensor data to control fuel injection, ignition timing, and emissions, while the PCM extends that oversight to the transmission. Together they keep the engine running smoothly and the gearbox shifting correctly. Proper operation is essential for fuel efficiency and emissions compliance. A typical failure may trigger internal diagnostic codes and cause a no\u2011start condition. Replacement modules such as <a href=\"https:\/\/www.fs1inc.com\/gm\/chevrolet-pcm-ecm-ecu-engine-computer\/spark-engine-computers.html\">Spark engine computers<\/a> are designed to match the vehicle&#8217;s software architecture.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>Where the PCM Is Located and What Replacement Involves<\/h2>\n<p>Both the ECM and PCM are mounted in the engine compartment and are accessed by disconnecting the battery, removing a few fasteners, and pulling the unit toward the firewall. The factory book time lists 0.8\u202fhours for removal and installation of each module. After the unit is secured, a 0.5\u2011hour relearn procedure is required to synchronize the new computer with the vehicle&#8217;s existing sensors and actuators.<\/p>\n<figure style=\"margin:22px auto;text-align:center;max-width:720px\"><img decoding=\"async\" style=\"max-width:100%;height:auto;border:1px solid #e2e6ec;border-radius:8px\" src=\"https:\/\/www.fs1inc.com\/blog\/wp-content\/uploads\/2026\/07\/2014-chevrolet-spark-pcm-location-diagram.webp\" alt=\"2014 Chevrolet Spark PCM location diagram\" loading=\"lazy\"\/><figcaption style=\"font-size:13px;color:#667085;margin-top:8px\">PCM mounting location on the 2014 Chevrolet Spark.<\/figcaption><\/figure>\n<div style=\"background:#f7f9fc;border:1px solid #e2e8f2;border-radius:10px;padding:18px 24px;margin:18px 0\">\n<h3 style='margin-top:0'>How to Reach the PCM on the 2014 Chevrolet Spark<\/h3>\n<ol style=\"margin:14px 0 6px 0;padding-left:26px\">\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> any debris from around the control module connector.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Position,<\/b> and all electrical loads must be OFF before servicing any electrical component.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Disconnect<\/b> the negative battery cable to prevent an electrical spark should a tool.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the battery.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the engine control module (ECM) bracket retaining bolt.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Release<\/b> the ECM connector locking lever and disconnect the ECM connector.<\/li>\n<li style=\"margin:10px 0;line-height:1.65\"><b>Remove<\/b> the ECM retaining nut from the ECM bracket and remove the ECM.<\/li>\n<\/ol>\n<p style='margin:10px 0 0 0'><em>Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.<\/em><\/p>\n<\/div>\n<table style=\"width:100%;border-collapse:collapse;margin:18px 0;font-size:15px\">\n<tr>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Operation<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Configuration<\/th>\n<th style=\"border:1px solid #d6dbe3;background:#f2f5f9;padding:9px 12px;text-align:left\">Book Time<\/th>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.8 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Engine Control Module Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.5 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Powertrain Control Module R&amp;R<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.8 hr<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">Powertrain Control Module Relearn<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">All configurations<\/td>\n<td style=\"border:1px solid #d6dbe3;padding:9px 12px\">0.5 hr<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<div class=\"info-section\">\n<h2>Programming Requirements After Replacement<\/h2>\n<p>Factory reprogramming of the Spark&#8217;s control modules calls for calibrated equipment, the correct software version, and a verification of the vehicle&#8217;s calibration data.
